Refined carrageenan has a 2% maximum for acid-insoluble material and is produced by alcohol precipitation or potassium chloride gel press process. [19] Semi-refined carrageenan has a much higher cellulose content [21] and is produced in a less complex process. Indonesia, the Philippines, and Chile are three main sources of raw material and ...
Gelation is promoted by gelling agents. Gelation can occur either by physical linking or by chemical crosslinking. While the physical gels involve physical bonds, chemical gelation involves covalent bonds. The first quantitative theories of chemical gelation were formulated in the 1940s by Flory and Stockmayer. Critical percolation theory was ...
Potato starch slurry Roux. A thickening agent or thickener is a substance which can increase the viscosity of a liquid without substantially changing its other properties. Edible thickeners are commonly used to thicken sauces, soups, and puddings without altering their taste; thickeners are also used in paints, inks, explosives, and cosmetics.
Mastocarpus stellatus, commonly known as carrageenan moss or false Irish moss, [1] [2] is a species in the Rhodophyceae division, a red algae seaweed division, and the Phyllophoracea family. M. stellatus is closely related to Irish Moss ( Chondrus crispus ).
Gellan gum is also used as gelling agent in plant cell culture on Petri dishes, as it provides a very clear gel, facilitating light microscopical analyses of the cells and tissues. Although advertised as being inert , experiments with the moss Physcomitrella patens have shown that choice of the gelling agent— agar or Gelrite—does influence ...
Gelling sugar or (British) Jam sugar or (US) Jelly sugar or sugar with pectin is a kind of sugar that is used to produce preserves, and which contains pectin as a gelling agent. It also usually contains citric acid as a preservative , sometimes along with other substances, such as sorbic acid or sodium benzoate
Stabilizers, thickeners and gelling agents, like agar or pectin (used in jam for example) give foods a firmer texture. While they are not true emulsifiers, they help to stabilize emulsions. Sweeteners Sweeteners are added to foods for flavoring.
Humans have used natural gums for various purposes, including chewing and the manufacturing of a wide range of products – such as varnish and lacquerware.Before the invention of synthetic equivalents, trade in gum formed part of the economy in places such as the Arabian peninsula (whence the name "gum arabic"), West Africa, [3] East Africa and northern New Zealand ().
